Final answer:
To solve for the number of azaleas purchased, set up a system of equations and solve by elimination. After simplifying, it's found that 20 azaleas were bought.
Step-by-step explanation:
To find out how many azaleas were bought when 36 plants were purchased in total, and taking into account that each azalea costs $5.00 and each crepe myrtle costs $8.00, you can set up a system of equations based on the given information. Let A represent the number of azaleas and C represent the number of crepe myrtles bought.
The two equations representing the scenario will be:
- A + C = 36 (because 36 plants were bought in total)
- 5A + 8C = 228 (because the total amount spent on plants is $228)
To solve the system, you can multiply the first equation by 5 to eliminate the variable A:
- 5A + 5C = 180 (1st equation multiplied by 5)
- 5A + 8C = 228 (2nd equation)
Subtracting the first new equation from the second equation, we get:
3C = 48
C = 16
Substituting C back into the first original equation:
A + 16 = 36A = 20
Thus, the number of azaleas bought is 20.
